9 January 1909:

Shackleton’s attempt to reach the South Pole from the Nimrod Expedition. The party reached what he called his “Furthest Point South,” 88º 23 S. 162º E.; 97.5 nautical miles from the South Pole. This was the furthest point south reached by anyone at that time. They planted the flag and left a box of Shackleton’s Antarctic stamps, then turned around for the return to base.
